'WILLIAM R. BARTON, OF BRIDGEWATER, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO GEORGE O. HAMMOND, OF CENTRAL FALLS, R. I.

EDGE-PLAN E.

SPECIFICATIN forming part of Letters Patent No. 236,759, dated January 18, 1881.

Application filed November 24, 1880.

To all whom t may concern:

Be it known ,that I, WILLIAM R. BARTON,

a citizen of the United States, residing at Bridgewater, inthe ycounty of Plymouth and State of Massachusetts, have invented new and useful Improvements in Edge-Planes, of which the following is a specification.

This invention relates to an improvement in edge-planes which are adjustable for operation upon edges of different thickness. Its objects are to simplify the construction of such tools, to render them more convenient for use than heretofore, to enable the cutting-edges to be kept sharp throughout and in condition for work upon-the edges to which they are especially adapted, and to secure uniformity of finish to the edges of' any number of soles.

An adjustable edge-plane has been heretofore provided with a cutting-bit having one inishin g lip or ilange stationary and the other adjustable, so that the extent of cutting-edge of the bit between the finishing lips or anges may be varied to suit edges of' different thickness. It is difficult to keep the bit of such a tool in proper order, for when it has been used upon a sole of a given thickness a portion of the cutting-edge is thereby dulled, and the entire edge must be ground to uniformity before it can be used upon a thicker sole, and even when used for a long time upon a comparativelynarrow sole a great portion of the edge of the bit must be ground and reground without being used, in order to keep it in its original shape. Besides,itisquite difficult to again adjust the movable lip to the exact gage of a class of soles upon which it has been previously used, so that there is a liability to be a lack of uniformity in edge-finish between the soles of two lots of shoes when uniformity is desirable. Further, when the tool is in use the unused portion of the bit and its holder projects outward beyond the edge of the sole and prevents the operator from having a good view of his work.

In accomplishing its objects and remedyin g the defects of the old style of' tool, as above set forth, my invention consists in a baseplate adapted to be connected with a suitable handle, and provided at one edge or side with 5o a vertical stationary jaw, the base-plate serv- (Model.)

ing to receive and support a movable jaw, which is capable of lateral adjustment in relation to the stationary jaw, both of said jaws being provided with means for holding the longitudinal edges of bits of varying width. It also consists in a novel construction and arrangement of a throat-piece to co-operate with different-sized bits, and in certain novel constructions and arrangements of devices whereby the various parts of the plane are 6o properly adj usted, and which will be hereinafter particularly described.

In the accompanying drawings, Figure 1 is an inner side view of an edge-plane constructed according to my invention. Fig. 2 is a front 65 view of the same. Fig. 3 is an outer side view.4 Fig. 4 is a rear view. Fig. 5 is a perspective view of the bit and the several portions of the the bit-holder and gages detached.

The letter A designates the handle, and B 7o the stationary portion of the bit and gage holder. This stationary portion consists of a base-plate, b, having at one end a lug, c, projecting at a right angle, and provided with a screw-hole, while the other end of said plate is bent slightly in the same direction as the lug, and has a transverse oblique-bottomed guide-groove, d, ormed across its inner surface, and a slot, e, cut through from said groove, the outer surface of the end of the plate being 8o beveled to form a seat for the head of a screw which passes through said slot, and which will be hereinafter referred to. From one side of the plate b, at its grooved and slotted end, a stationary jaw, j', projects at a right angle, 85 and has its upper edge provided with an undercut lip, g, this stationary jaw and its undercut lip forming the stationary portion of the bitholder.

The letter f designates a movable jaw, hav- 9o ing its upper edge provided with an undercut lip, g', similar to that of the jaw f, and its lower edge is formed to fit transverselyin the groove d and extend across the upturned edge of plate b. The lower portion of the jaw f is thickened in order that it may be tapped with a screw-hole to receive a suitable-sized screw,

h, which, when said movable jaw is arranged with its lower edge in the groove and across the end edge of the plate, passes through the I@ slot e and into said hole for the purpose of securing the movable jaw in any position to which it may be adjusted. The jawsfandf are provided with coincident holes i i', the hole 5 'i' in the movable jaw being screw-threaded to engage the screw k, and the hole i in the stationary jaw being smooth and of proper size to let the shank of said screw pass loosely through it. The parts being thus placed, the 1o movable jaw may be adjusted to or from the stationary jaw by turning the screw as required.

The letter L designates a bit having a cutting-edge, l, and side-finishing flanges m m, x5 Which, as is well known, may have any trailsverse contour desired. The outer edges of these anges are beveled to fit under the undercut portions of the lips g and g' of the jaws ff', and the bit will be iirmly held by said 2o lips when its edges are placed thereunder. as shown clearly in Fig. 4, and the movable jaw properly adjusted and secured. Bits of dit'erent widths may be used, according to the thicknesses of the edge to be planed; and, as will be seen, said bits lnay be adjusted longitudinally, according to the cut desired, and to compensate for the wear ofthe cnttingedges. Each bit and its llanges being made in one piece, it is obvious that a uniform tinish is produced upon all edges upon which a given bit is used; and though removed and replaced, its Work will be the same, no adjustment ot' the extent of its cutting-edge being required; and being ofproper width forits special work, there will be no portion projecting outward beyond the sole and obstructing the operators view of the work.

Thelongitudinal adjustmentofthc bit is made with respect to a tl11'oat-piece, N, the workingface of which corresponds approximately in transverse contour with that ot' the bit. and is provided with a stationary flange, n, which corresponds to the flanges of the bit which rests upon the stationaryjawf. The other tlange, o, of the throat-piecc is adjustable, and is provided at its outer end with a slotted lug, o', extending at an angle therefrom and resting upon a shoulder, p, of the throatpiece, upon which it is adjustable, a screw, p', passing through the slot of said lug and into the throat-piece, serving to hold it in position, and permitting its adjustment to bring the flange o into coincidence with the corresponding ilange of the bit used. The inner surface of the lower portion of the throat-piece is recessed to embrace the lug c ofthe plate b, which lug thus serves as a guide upon which the throat-piece is adjustable, and to which it is secured by means of a screw, q, passing through a slot, q', in its said lower position, and into the screw-hole c of the lug. When a bit of the. desired width is secured between the jaws the throat-piece is to be adjusted to fix the proper cut, and then the ilange o, by moving the lug o', is brought to coincide with the corresponding 65 [lange of the bit.

What I claim is- 1. ln an edge-plane, the combination, with a base-plate adapted to be connected to a handle and provided at one side with a vertical stationary jaw, of a vertical movable jaw capable of adjustment on the baseplate in relation to the stationary jaw, both of said jaws heilig provided with means for holding the longitudinal edges of bits ot' varying width, substantially as described.

2. ln an edge-plane, the combination, with the throat-piece provided with the stationary ilange and an adjustable flange, of devices for holding bits ot'dit'erent widths, substantially as described.

3. The combination, with the baseplate b, provided with the lug c, groove d, and stationary jawf, having the undercutlipg, ofthe adjustable jawf, having a similar undercut lip, and the adjustable throat-piece and adjustable tlange, substantially as described.

In testimony whereof' I have hereunto set my hand in the presence of two subscribing witnesses.
